Filament eruption, spotless Sun, Total Solar Irradiance and cosmic radiation

A 13-degree long plasma filament eruption was observed in SDO/AIA 304 imagery starting at 12:29 UTC on December 15, 2017. A glancing blow is expected late December 19, in combination with a recurrent, positive polarity CH HSS. Meanwhile, solar activity is at very...

Atmospheric radiation increasing as we head into Solar Minimum

Cosmic rays from deep space are increasing almost unabated as the Sun's magnetic field weakens and we head into Solar Minimum. As reported by Spaceweather.com, the stratospheric balloons they've been flying together with the students of Earth to Sky...

Remarkable pink aurora outburst over Norway

Over the past couple winters, big displays of pink and white auroras have coincided with spotless suns. The sight is often big enough to make observers wonder if there is a connection, SpaceWeather reports. The most recent remarkable outburst of pink auroras was...

Solar minimum surprisingly constant

Using more than half a century of observations, Japanese astronomers have discovered that the microwaves coming from the Sun at the minimums of the past five solar cycles have been the same each time, despite large differences in the maximums of the cycles. In...

Intensifying cosmic rays, grand solar minimum and Earth's climate

Data provided by the students of Earth to Sky Calculus and Dr. Tony Phillips of SpaceWeather.com show cosmic ray levels are intensifying, as the Solar Minimum approaches, with an approximately 13% increase since March 2015. This article provides a brief overview of...

Spotless Sun heralds Solar Minimum after CME producing Region 2567 departs

After Active Region 2567, the source of 7 M-class and numerous C-class solar flares between July 21 and 24, rotated away from the visible disk, our Earth facing Sun is again spotless. This is the third 'spotless Sun' since June 3, and although it is a...

Cosmic ray intensification trend continues

An intensification trend of cosmic rays activity reported last month by SpaceWeather.com continues. The latest balloon flight over California on February 5 observed the highest value yet. The gathered data shows that cosmic rays in the mid-latitude stratosphere are...

Cosmic radiation intensifying as we enter another Solar Minimum

An increased activity of cosmic rays has been observed around the Arctic Circle by the neutron monitors during the last year. The same trend was also noted in an independent measurement project carried out by the Spaceweather.com and the students of Earth to Sky...

Why Europe will soon be cold?

Russian scientists regained solar activity over the past thousand years and made the forecast to the year 3200. What is the climate waiting for Russia and Europe in 15 - 20 years? Will be there weather abnormalities in the coming decades? Will some areas experience...

Earth-facing side of the sun without visible sunspots

Images taken by Solar Dynamics Observatory (SDO) on July 17, 2014 show no active sunspots on the visible solar disk. To be correct, tiny decaying AR 2113 is still visible, but its size remains so small that the plots and charts didn't registered it. SDO's

Ben Davidson: The Variable Sun and Its Effects on Earth - EU2014

The message has been loud and clear for many years—a community of scientists insisting that human activity is warming our planet, taking humanity to the edge of a precipice. But now, as science begins to understand earth's place in the electric solar system, t

Why current climate is anomaly, and ice age climate is normal Earth's climate

The Ice Age isn't coming, because it is already here. According to author and researcher Rolf Witzsche the Ice Age Climate is the normal climate for the Earth and it has been for more than 85% of the last million years. Because glaciation

Solar cycle 24 on its way

Science has only just begun to understand how cyclical changes in the Sun effect Earth's weather and climate. But the more technological human society grows, the more vulnerable we may become.Activity on the Sun is due to reach its peak around early 2014, so expect

Geomagnetic storm in progress

UPDATE: The Geomagnetic Storm has subsided over the past few hours. However, the solar wind remains energized and occasional pulses of activity are expected for another 24 hours. Region 1283, the responsible party back at the Sun, decayed today. The Geomagnetic Storm

Solar radio bursts

This week's sharp increase in solar activity has turned the Sun into a radio transmitter. Bursts of shortwave static are coming from the unstable magnetic canopy of sunspot 1283. Yesterday in New Mexico, amateur radio astronomer Thomas Ashcraft recorded some...

New insights on how solar minimums affect Earth

Since 1611, humans have recorded the comings and goings of black spots on the sun. The number of these sunspots waxes and wanes over approximately an 11-year cycle - more sunspots generally mean more activity and eruptions on the sun and vice versa. The number of
